The Long Short-Term Memory (LSTM) cell can process data sequentially and keep its hidden state through time. Long short-term memory ( LSTM ) [ 1 ] is a type of recurrent neural network (RNN) aimed at mitigating the vanishing gradient problem [ 2 ] commonly encountered by traditional RNNs.
Specifically, for a wide-sense stationary time series, the mean and the variance/autocovariance are constant over time. Differencing in statistics is a transformation applied to a non-stationary time-series in order to make it stationary in the mean sense (that is, to remove the non-constant trend), but it does not affect the non-stationarity ...

The time series included yearly, quarterly, monthly, daily, and other time series. In order to ensure that enough data was available to develop an accurate forecasting model, minimum thresholds were set for the number of observations: 14 for yearly series, 16 for quarterly series, 48 for monthly series, and 60 for other series.
